INSTALLATION INSTRUCTIONS
SEE WARNING ON CARTON
GENERAL INFORMATION, CONDUIT MOUNT:
All 12” (304.8 mm) minimum supply wire outside of conduit.
Fixture housing conduit threads are 3/4-14 NPS.
Use a waterproof pipe joint compound (by others) for all entries into
housing.
Plug all unused entries into housing (if applicable).
CEILING/FLUSH MOUNT: (See Figures 1d, 2, and 3)
1. To ease installation, top cover (1) should be removed from the fixture
assembly. Unfasten the latch (2) and the top cover casting can be
removed from the hinge pin assembly (3).
2. Feed electrical supply wire through the appropriate threaded hole/hub
in the top cover and thread conduit into the top cover until tight. For
applications using “thru-wiring” all conduit should be attached to the
top cover.
3. Attach top cover to ceiling using recommended hardware, BUT DO
NOT TIGHTEN THE TOP COVER TO THE CEILING. Clearance
between the fixture housing and the ceiling is necessary at this point.
4. Fixture ground wire connection can be made with supply ground at this
point if desired.
5. Lift fixture assembly and place the hinge pin (3) in the cradle (4) of the
top cover casting. There should be enough clearance between the
hinge cradle and the ceiling to allow the hinge pin placement. The
fixture can now hang from the hinge pin.
6. TIGHTEN THE TOP COVER TO THE CEILING.
7. Make remaining wiring connections. See appropriate WIRING
SCHEMATIC for reference. If ground wire was not connected earlier,
connect the fixture ground with the incoming ground wire. There will
be a single white and a single black wire providing power to the entire
array of LED drivers. Incoming power to be connected to the white
wire and the black wire. See warnings above about wire connections.
8. Dress wires as needed.
9. Gently pivot the assembly up until the lower portion of the fixture is
against the top cast cover. The lower portion of the fixture should
“nest” inside the fixture cover (1). The orange sealing gasket (5)
should compress evenly as well.
10. Swing wire bail of the latch (6) over the top cover at the latching point
(7).
11. Press the latch lever (8) to draw the two halves of the fixture together
and seal.
YOKE MOUNT: (See Figures 1e, 2, and 3)
1. Yoke mounting bracket (9) is shipped with the fixture, but is not
assembled at the factory. Mounting hardware is also included.
2. Position the yoke as shown in Figure 1e, lining up the mounting holes
of the yoke with the drilled and tapped holes in the fixture housing.
3. Attach the yoke to the fixture housing loosely, using the flat washers,
lock washers, and ¼-20 screws.
4. To ease installation, top cover (1) should be opened/removed from the
fixture assembly. Unfasten the latch (2) and the top cover casting can
be opened/removed from the hinge pin assembly (3).
5. Feed electrical supply cord (customer supplied) through the strain relief
(10) and reducer bushing (11) and through the threaded hole in the top
cover.
6. Fixture wiring to supply wiring can be completed at this point (see
WIRING SCHEMATIC for reference).
7. To help with wire management, eliminate slack in the electrical cord
inside the fixture before completely threading the strain relief into the
reducer bushing. Thread the strain relief /reducer bushing into the top
cast cover until tight.
8. Tighten set screw located on conduit hub inside the cover to prevent
rotation of the strain relief.
9. Determine final position of yoke mounting bracket and then tighten all
hardware.
